HEADLIGHT DIMMER.

Application filed April 20, 1922. Serial No. 555,716.

To all whom it may concern:

Be it known that I, JAY D. .JoNEs,'a citizen of the United States, and resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Headlight Dimmers, of which the following is a specification.

The object of my invention is to produce a head light dimmer of novel form which may be located within the head lightwithout reconstruction of the head light structure, said dimmer being arranged to effectually eliminate the glare of the head light, said dimmer at the same time being arranged to deflect amaximum amount of light forwardly and downwardly.

A practical embodiment of my invention is represented in the accompanying drawings, in which Fig. ,1 represents a vertical longitudinal central section through a head light of usual form, with my improved dimmer located therein.

Fig. 2 represents a front view of the same.

Fig. 3' represents a detail side view of the dimer,

The head light comprises the usual casing 1, the reflector 2, the high power central lamp-3 andthe low power oflset lamp 4. The lens 5 is-located between the inwardly directed flange 6 of the rim 7 and the outwardly directed stepped flange 8 of the reflector 2, and is secured in position by the brackets 9 and fastening screws 10.

My improved dimmer is located within the head light immediately back of the lens 5, the dimmer illustrated comprising a forwardly flaring ring 11 having a circumferential flange l2 directed outwardly from the front of the said ring and positioned between the lens 5 and reflector flange 8.

The dimmer ring is provided with a plurality of rearwardly and upwardly inclined fixed vanes 13 of considerable depth extending in parallelism across and spaced between the opposite sides of the ring, the lower front edges of the vanes being located substantially in the front plane ofthe ring and the upper rear edges being located in different vertical planes rearwardly of the back plane of the ring. These vanes 13 overlap in horizontal planes and decrease self to the particular embodiment in depth from the middle to the top and bottom vanes. The upper rear edges of certain of the vanes are cut away to form spaces 14 into which the lamps 3 and 4-project,thus permitting the vanes to extend a considerable distance into the interior of the reflector shields 16,-17, being provided to prevent the exposure of the lamps through the vanes in a horizontal plane.

A light intercepting plate 15 is provided across the top of the front of the flaring ring 11 to screen the light rays above the to end 12.

. y causing the vanes to overlap in a horizontal plane I am enabled to eliminate all glare, the rays being deflected by the vanes downwardly and forwardly. -Also by providing vanes of considerable depth I am enabled to use fewer vanes well spread apart, thus allowing the maximum quantity of light to be thrown downwardly and forwardly from the head light.

Furthermore, it will be seen that I have provided a dimmer which is very simple in construction, inexpensive to manufacture and easily positioned within the headlight without interfering with the main or auxiliary lamps, the deflector at the same time being very strong and rigid and suitable for use in connection with-head lights now in common use, without any redesigning or reconstruction of the said head lights. Furthermore, the deflector is carried by the lamp front, whereby ready access may be obtainedfor the replacing of lamps, the polishing of the reflector, etc.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without "departing from the, spirit and scope of my invention, hence I do not wish to limit myherein shown and described, but

What I claim is A dimmer for location within a head light including a forwardly flaring ring carrying a plurality of parallel rearwardly and upwardly inclined overlapping vanes of a considerable depth spaced a considerable distance apart, the lower front edges of the vanes being located substantially in the front plane of the ring and the upper rear edges being located in difi'erent Vertical planes-rearwardly of the back plane of the ing plate across the top of the front of the ring the upper rear edges of certain of the flaring ring to screen the light rays above vanes being cut away to form spaces into the top vane of the dimmer. 10 which the central and offset lumps projects, In testimony, that I claim the foregoing stshields carried by certain of the vanes for as my w n oml have slgned my name thls preventin the exposure of the lamps 17th day of Apnl, 1922.

through t e dimmer, and a light intercept- JAY D. JONES.
